Being a (recovering) engineer I have as much or more appreciation for specific output achievements (power or torque per displacement) in either NA or FI engines. High specific outputs are a mark of engineering sophistication and excellence (even more so in the NA realm for obvious reasons). High specific outputs aren't all that magical with really large turbos and the accompanying severe lag is the price to pay as there is no such thing as a free lunch...
Now that being said, in the real world, specific output doesn't makes a lick of difference. Mpg might be the only counter to that position (however much that may matter to most enthusiasts...) Look the the mpg that modern large displacement Corvettes can obtain. The only other benefit for specific output is tax reasons (in the EU and other places where tax is based on displacement) or in racing where there are displacement limitations or other requirements favoring FI. But again those aren't very "real world" for us as US consumer enthusiasts.
